ANDREW vrrnnxo on NEW YORK, n. Y.

PARAFFIN -PRESS-PLATE-SEPARATING DEVICE.

Application filed March 20, 1925. Serial N0.'16,941.

To all whom it may concern:

Be it known that I, Annnnw VrrENKo, a citizen of Russia, residing at New York, in the county of New York and State of New York, have invented certain new and useful For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various nove features of the invention are more particularly set forth.

Fig. 1 of the drawing is a side elevation of my improved machine.

Fig. 2 is a plan view thereof, with parts in horizontal section.

Fig; 3 is a transverse sectional view taken on the'line 38 of Fig. 1. v

Fig. 4e a detail transverse elevational view showing the gear connections from the motor to the scrubber knife.

Fig. 5 is a detail horizontal sectional view taken on the line 55 of Fig. 1.

Fig. 6 is a detail face elevational view of the scrubber knife, showing also the worm devices for reciprocating it.

Fig. 7 is a detail edge view of the knife.

Fig. 8 is a fragmentary transverse sec tional view showing the knife-engaged with one of the paratlin molds.

Referring now to the drawing, the machine comprises an elongated frame comprising the end standards 10, and the longitudinal side bars 11 that are rigidly fixed at their ends to the said standards, these side bars being formed with rack teeth 12 as shown. Extending longitudinally of the machine, and located inwardly of the side bars 11, are the two rods 14 which are-f xed at their ends to the standard Upon these rods are supported the plates on which the p'araifin has been formed, these plates being of ordinary construction and comprisingthe canvas blankets 15 folded over the metal plates 16 and having the paraflin retaining frames or rings 17 on one-face thereof. During the forming of the parafiin these plates are all compressed into asolid mass in the press. Thesepl-ates are formed with hooked lugs 18 on opposite sides thereof whereby they. are supported by and between the rods 14, the rings 17 having like hooks that engage over the said rods.

The means for removing the paraffin com- .prises a pair of shafts 2O onwhich are formed with worms or helices 21. These shafts extend longitudinally of the machine and are supported at their ends in and by the legs 22 of a carriage having an upper platform 23 extending across the machine at a distance above the said bars '11. At

their lower ends the legs of'the carriage are provided wlthflanged rollers 24; that rest on the said bars which latter fornr runways for the carriage. Supported-on the platform 23 is an electric motor 25 having abevel pinion 26 on its rotor shaft. Meshing with this pinion arethe bevel pinions 27 on the innerends of a pair of transverse shafts 28 which have other bevel gears 29 on their remote'or outer ends engaged with bevel gears 30. These gears 30 impart motion to a pair of vertical shafts 8 l supported by the carriage at the sides thereof, and having-spur pinions 32 on their lower ends that engage with the rack bars 11 to move thecarriage along the machine. One of these gears 80 is fixed directly on its shaft 31 while the otherimparts movement to its shaft 31 through the medium of the meshing gears 33. To rotate the worm shafts 20 the vertical shafts 31 have fixed thereon theworm pinions 3% that mesh with worm gears 35 on the said shafts 20.

The scrubber knife, that removes the paraffin from the plates consists of'a compound blade that is arrangedin a vertical plane extending transversely to the machine, and is formed with a sharpened lower edge as shown. This blade is formed of a number of sections 40 fixed on the ends of a number of hollow rods or stems. 41 that engage freely in suitable aperturesin the bottom bar 12 of a frame elementof inverted T-form, thereby supporting the said blade or scrubber. Located within the rods 11 are the expansion springs such' as 13 that bear on the'blade at one end and at their other ends on pins 44 that are fixed on the bar 42 and pass transversely through longitudinal slots 45 in the said rods. This mounting of the blade permits the latter to move toward the bar or frame on which it is supported.

The'upright member 42 of the blade frame is formed on the sides thereof with worm teeth 47 that are engaged by worm pinions 48 that are mounted on vertical shafts 49 and are operated alternately in opposite directions from the motor 25 so as to give the blade a vertical reciprocatory movement. The connection between the shafts 49 and the motor comprises the sprocket wheels 52 fixed on the said shafts and having looped thereover chains 53 that engage over like wheels 54 fixed ona pair of stub shafts 55 supported by and above the platform 28, these shaftshaving the meshing spur gears 56 thereon whereby they are caused to rotate in unison. One of these shafts 55 has also fixed thereon another-spur gear 5? with which engage alternately the mutilated gears 58 and 59 located one .on each side thereof and having teeth extending over half their circumference. These gears 58 and 59 are driven in relatively opposite directions from the bevel gear 26 on the motor shaft by means of bevel gear 60 on a vertical shaft 61 that meshes with the said gear 26, this shaft 61 having fixed thereon a spur gear 62 engaged on one side by a working gear 63 and on the other side by an idler 64, the idler in turn meshing with a gear 65 corresponding to the gear (33 these gears 63 and 65 being fixed on the respective shafts of the mutilated gears 58 and 59. It will be apparent then that rotation of the motor shaft will cause the scrubber to be alternately raised and lowered, the mutilated gears alternately moving into drive engagement with the gear 57.

In the operation of my improved machine, the plates in which the wax is molded are hung on the rods 14. The motor being driven, the carriage is caused to advance along the i'nachine, while the worms 21 are caused to rotate. These worms engage the hooks 18 on the plates to move the same forward, and are formed with intermediate portions 21 of high pitch whereby the separated elements are moved out of contact with the solid mass, the knife or scrubber coming down and effecting the separation by engagement with the said plates.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent of the United States is as follows:

1. A machine of the class described comprising a frame having a pair of longitudinal supports for paratfin molds, a carriage supported on said frame to be movable along the said frame, and means on said carriage for separating individual molds.

2. A machine of the class described comprising a frame having a pair of longitudinal supports for paraffin molds, a carriage supported on said frame to be movable along the said frame, and means on said carriage for separating individual molds, saidmeans comprising rotary worms adapted to engage the said molds, and a vertically movable scrubber knife.

3. A machine of the class described comprising a frame having a pair of longitudinal supports for paraffin molds, a carriage supported on said frame to be movable along the said frame, and means on said carriage for separating individual molds, said means comprising rotary worms adapted to engage the said molds, and a vertically movable scrubber knife, and means resiliently supporting the said knife to permit of movement on its support transversely to the mold faces.

4. A machine of the class described comprising a frame having a pair of longitudinal supports for paraflin molds, a carriage supported on said frame to be movable along the said frame, and means on said carriage for separating individual molds, said means comprising rotary worms-adapted to engage the said molds, and a vertically movable scrubber knife, said worms having intermediate portions of relativ ly high pitch.

5. A machine of the class described comprising a frame having a pair of longitudinal supports for paraffin molds, a carriage supported on said frame to be movable along the said frame, and means on said carriage for separating individual molds, a motor on said carriage, rack bars on said frame, gear pinions on said carriage meshing with said rack bars, and drive connections between said motor and said gear pinions, and said motor and the said separating means.

(3. A machine of the class described comprising a frame having a pair of longitudinal supports for paraffin molds, a carriage supported on said frame to be movable along the said frame, and means on said carriage for separating individual molds, said means including a vertically movable scrubber knife having a vertical arm formed with worm teeth along the side thereof, a worm gear meshing with said teeth, a spur gear operatively connected to the said worm gear, and mutilated drive gears for said worm gear adapted to alternately mesh with the latter to rotate the same in relatively opposite directions.

In testimony whereof I have affixed my signature.
